I am not a cam expert but I don't think I would worry about the lift or duration change.
To me extra duration od 4 degrees doesn't sound massive.
The lost lift on the inlet is only 0.15mm (6 thousands of an inch.) The extra lift on the exhaust at 0.41mm is a bit more (16 thousands of an inch) but probably not an issue.
Get your feeler gauges out and see just how little this is.
